This application claims the priority of German Patent Document No. 10 2007 002 875.1, filed Jan. 15, 2007, the disclosure of which is expressly incorporated by reference herein.
The invention relates to a webbing-up device for webbing up a printing substrate web in a printing press, namely in a web-fed printing press.
A device for webbing up a printing substrate web in a web-fed printing press is known from German Patent Document DD 203 867 B, whereby, when setting up a web-fed printing press, this type of webbing-up device pulls a web-like printing substrate starting from a roller splicer through the printing units of the web-fed printing press. According to DD 203 867 B, the webbing-up device includes a finite webbing-up belt, which is conveyed by a drive roller to a take-up spool. In addition to webbing-up devices based on webbing-up belts, webbing-up devices are also known that are based on a finite conveyor chain, whereby the finite conveyor chain is made up of several chain segments connected to one another in an articulated manner, and whereby the conveyor chain is guided into a chain guide rail. In this regard, reference is made to Helmut Kipphan's Handbook of Print Media, Page 278, Springer Verlag, Year 2000.
The present invention relates to a webbing-up device for webbing up a printing substrate web in a printing press with a finite conveyor chain, which is guided into a chain guide rail. The chain guide rail is preferably installed throughout the entire printing press, whereby dirt can get deposited in the chain conveyor rail during printing operation, which can impede the malfunction-free transport of the conveyor chain of the webbing-up device through the chain guide rail during a subsequent set-up operation. This is a disadvantage.
Starting herefrom, the present invention is based on the objective of creating a novel webbing-up device for webbing up a printing substrate web in a printing press.
According to the invention, a cleaning device, which is detachably connected to the conveyor chain, is allocated to at least one end of the finite conveyor chain.
In terms of the present invention, a cleaning device, which is detachably connected to the conveyor chain, is allocated to at least one end of the finite conveyor chain. The cleaning device can be used to safely remove dirt that gets deposited during printing operation in the chain guide rail. As a result of this, malfunction-free operation of the conveyor chain is always guaranteed.
Preferred developments of the invention are yielded from the following description. Without being limited hereto, exemplary embodiments of the invention are explained in greater detail on the basis of the drawings.
The conveyor chain 11 of the webbing-up device 10 is guided into a chain guide rail 16, which is has a C-shaped contour in the depicted exemplary embodiment. The chain guide rail 16 is comprised of running surfaces 17 and 18, on which the runners 15 of the conveyor chain 11 roll when the webbing-up device 10 is in operation. Conveyor chain drive wheels (not shown) are used to transport the conveyor chain 11 along the chain guide rail 16, whereby preferably one conveyor chain drive wheel is positioned along the chain guide rail 16 on each of the defined positions of the chain guide rail.
In terms of the present invention, a cleaning device 19, which is connected to the conveyor chain 11 in a detachable as well as articulated manner, is allocated to at least one end of the conveyor chain 11 of the webbing-up device 10. According to
The cleaning device 19 features a rod-like and/or rectangular basic body 22. In the depicted exemplary embodiment, cleaning bodies 25 are allocated to two opposing side walls 23 and 24 of the basic body 22. The opposing running surfaces 17 and 18 of the chain guide rail 16 for the run wheels 15 of the conveyor chain 11 can be cleaned with the assistance of the cleaning bodies 25.
The basic body 22 of the cleaning device 19 is embodied of a material, which, on the one hand, is flexible enough for the basic body 22 and thus the cleaning device 19 to pass or run through all radii and/or curves and/or twists of the chain guide rail 16 without a problem and which, on the other hand, is rigid enough to securely accommodate the cleaning bodies 25 and absorb the mechanical stress that arises. The basic body is preferably fabricated of a plastic.
In the exemplary embodiment in
Openings 26 are made in the basic body 22 of the cleaning device 19, in which the conveyor chain drive wheels can engage during transport of the conveyor chain 11 and thus the cleaning device 19 along the chain guide rail 16. According to
As can be seen best in
The bristles of the lateral bundle of bristles, on the other hand, are set diagonally relative to the side walls 23 and 24 in order to also be able to securely clean the edges and/or corners of the running surfaces 17 and 18 of the chain guide rail 16.
As already explained, the cleaning device 19 is fastened at one end to an end of the finite conveyor chain 11. The printing substrate web is fastened to the conveyor chain. However, it is also technically realizable to fasten the printing substrate web to the cleaning device 19.
In the exemplary embodiment in
It is just as possible to allocate cleaning bodies that are embodied in different ways to the side walls 23 and 24 of the basic body 22 of the cleaning device 19. As a result, it is then possible to loosen dirt from the running surfaces 17 and 18 of the chain guide rail 16 using the first cleaning bodies, e.g., via strippers or scrapers, and to gather up or carry away the loosened dirt with the second cleaning bodies, e.g., bundles of bristles.
Because of the fact that the cleaning device 19 is connected in a detachable manner to one end of the finite conveyor chain 11, the cleaning device can be easily assembled and disassembled from the conveyor chain 11.
As a result, it is possible to use the cleaning device 19 in a targeted manner, e.g., only in defined sections of the chain guide rail 16, in order to prevent dirt from one area of the chain guide rail 16 from getting into another area of the chain guide rail via the cleaning device 19 and thereby enabling the different dirt particles that are accumulating in the different areas to blend into a mixture, which is harder to remove than the individual dirt particles.
The foregoing disclosure has been set forth merely to illustrate the invention and is not intended to be limiting. Since modifications of the disclosed embodiments incorporating the spirit and substance of the invention may occur to persons skilled in the art, the invention should be construed to include everything within the scope of the appended claims and equivalents thereof.
